3 Claims.

The invention relates to spindles and has for its primary object the provision of an improved spindle adapted to be mounted detachably in mechanism for driving and journalling it.

A spindle embodying a preferred form oi the invention is adapted for use in duplicating machines of the hectograph type, the spindle being adapted to have a hectograph band wound upon it. The spindle and band may be removed from the duplicating machine as a unit whenever it becomes necessary to replace the band and improved means are provided on the spindle for mounting it in the machine.

Other objects and advantages will become apparent as the following detailed description progresses, reference being had to the accompanying drawing, wherein- Fig. 1 is a side elevation of the improved spindle, the spindle being shown assembled With mechanism for rotating and journalling it.

Fig, 2 is a fragmentary elevation of the improved spindle.

Fig, 3 is an end elevation of the improved spindle, and

Fig. 4 is a side elevation of the spindle shown by itself.

Referring to the drawing wherein a spindle embodying a preferred form of the invention is shown, the improved spindle is designated generally by the reference character I0. The spindle preferably comprises a body portion II formed of wood and to one end of the body portion II a metallic bracket member I2 is secured by a pin or rivet I3. The bracket member I2 comprises a cap-like portion III which telescopes over one end of the body portion I I. Formed integral with the cap-like member I4 is a lug I5 provided at its free end with a boss I6 from which a screwthreaded pin I'I projects, the pin I'I preferably having a portion thereof embedded in the boss I6 and being of a smaller diameter than the boss so that an annular shoulder I8 is provided. However, the pin I'I may be formed integral with the boss if it is so desired. The pin I'I `extends at a right angle to the axis of rotation of the spindle.

The spindle Ill is shown assembled with parts of a duplicating machine of the hectograph type. It will be noted that the pin I'I projects through a lug 20 and that nuts 2I screw-threaded upon the pin I'I clamp the lug 20 against the annular shoulder I8, The lug 20 is formed integral with a shaft 22 rotatably journalled in a bearing 23.

Means (not shown) is provided for driving the shaft 22 which, in turn, drives. the spindle.

At its other end, the body portion I I has a bore 25 formed in it, which bore accommodates one end of a shaft 26 which is journalled in a bearing 2'I. A pin 30 extends through the shaft 26 and the last mentioned end of the body portion II abuts against it.

A hectograph band (not shown) may have one of its ends secured to the body portion II and the band may be wound thereon. When the band has been unwound from the spindle I0 it may be rewound thereon by rotating the spindle I0 through the medium of the shaft 22.

I claim:

1. In a hectograph winding spindle mechanism, the combination of a spindle member, means detachably connected with one end portion of said spindle member for rotatably supporting it, a shaft member rotatably mounted opposite the other end of said spindle member, and means releasably connecting said shaft member with said spindle member, comprising a transversely perforated lug carried by one of said members in centered position with respect to the axis of rotation, and a transversely extending pin xedly mounted on the other member adapted by releasable connection with said lug to hold said members in axial alignment with each other.

2. In a hectograph winding spindle mechanism, the combination of a spindle member in the form of a cylinder having a socket in concentric posi tion in one end, a pin upon which said socket is adapted to be slipped for rotatably supporting that end of the spindle member, a shaft member rotatably mounted opposite the other end of said spindle member, a transversely perforated lug carried by said shaft in centered position with respect to the axis of rotation of the shaft, an arm carried by said spindle member at said other end eccentrically thereof so as to support said spindle member from said lug in concentric position with respect to said shaft, a pin xedly mounted on said arm in position to extend through the opening in said lug, and detachably mounted means for holding said pin in operative engagement with said lug.

3. A winding spindle for a hectograph machine, comprising in combination a body portion having a socket in concentric position in one end, a cap on the opposite end of said body portion having an arm at one side face extending beyond the end o-f the body portion, and a pin xedly mounted on said arm and extending transversely of the spindle diammetrically thereof.
